A sailboat traveled 30 miles in 2.5 hours. At the same speed, how far can the boat sail in another 4.5 hours ?

Ivanshal [37]

54 miles

using the formula

speed = $\frac{distance}{time}$ = $\frac{30}{2.5}$ = 12 mph

continuing at 12 mph then

distance = speed × time = 12 × 4.5 = 54 miles

Geometry problem help, will reward brainly! both dont have to be solved, but id really appreciate it.

Anastaziya [24]

Answer:

height: 8 m
slant height: 5 in

Step-by-step explanation:

The parameter of interest can be found by putting the given values into the appropriate volume or area formula for a pyramid, then solving for the unknown. The relevant formulas are ...

V = 1/3s²h . . . . . s is the base length; h is the height

A = s(s +2h) . . . . s is the base length; h is the slant height

__

<h3>height given volume</h3>

Using the given values for the volume and the length of the base, the formula becomes ...

V = 1/3s²h

96 m³ = 1/3(6 m)²h . . . . . . . . . . use the given values for V, s

(96 m³)/(12 m²) = 8 m = h . . . . . divide by the coefficient of h

The height of the pyramid is 8 meters.

__

<h3>slant height given area</h3>

Using the given values for area and the length of the base, the formula becomes ...

A = s(s +2h)

47.25 in² = (3.5 in)(3.5 in + 2h) . . . . use the given values for A, s

13.5 in = 3.5 in + 2h . . . . . . . . . . . divide by 3.5 in

10 in = 2h . . . . . . . . . . . . . . . . . subtract 3.5 in

5 in = h . . . . . . . . . . . . . . . . divide by 2

The slant height of the pyramid is 5 inches.

Whats the radius of a sphere if its volume is 1928pi

mojhsa [17]

Answer:

Cube root of 1446

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3} \pi r^3$ . Therefore, if we divide 1928pi by 4/3pi and then take the cube root, you will find the radius. In this case, 1928pi/(4pi/3)=1446, meaning that the radius is the cube root of 1446. Hope this helps!
